A pharmacy technician is preparing a sterile IV admixture in a laminar airflow workbench (LAFW). The technician notices a small crack in the workbench's HEPA filter. What is the MOST appropriate immediate action?
- AApply sterile tape over the crack until a replacement filter arrives.
- BSwitch to a nearby biological safety cabinet (BSC) without further inspection.
- CContinue compounding, but work more slowly and carefully.
- DImmediately stop all compounding in the LAFW and report the issue.
Show answer & explanationAnswer & explanation
Correct answer: D. Immediately stop all compounding in the LAFW and report the issue.
A cracked HEPA filter compromises the sterility of the compounding environment. Continuing to compound would risk microbial contamination of sterile products, posing a significant patient safety hazard. All operations must cease, and the issue must be reported for immediate repair or replacement.
Why the other options are wrong
- A. Sterile tape is not an effective or validated repair for a HEPA filter and does not restore its integrity.
- B. Switching to another hood without proper assessment of its certification and suitability for the task is not a safe or appropriate primary response.
- C. Working more slowly does not mitigate the contamination risk from a compromised filter.
HEPA Filter Integrity
The ability of a High-Efficiency Particulate Air (HEPA) filter in a cleanroom or workbench to effectively remove airborne particles, ensuring a sterile environment.
- Critical for sterile compounding.
- Damage compromises sterility.
- Requires immediate action if integrity is breached.
